ACCEL Project Embodied Media Such media that a human user has his or her avatar body in an environment that the media mediates such as a computer generated information environment or a remote real environment and he or she is able to act using the avatar body as his or her own body in the environment. Virtual Reality and Telexistence are the typical examples of Embodied Media.
History[ edit ] One of the earliest applications of haptic technology was in large aircraft that use servomechanism systems to operate control surfaces. Here, the missing normal forces are simulated with springs and weights. In lighter aircraft without servo systems, as the aircraft approached a stall the aerodynamic buffeting vibrations was felt in the pilot's controls.
This was a useful warning of a dangerous flight condition. This control shake is not felt when servo control systems are used. To replace this missing sensory cuethe angle of attack is measured and when it approaches the critical stall point, a stick shaker is engaged which simulates the response of a simpler control system.
Alternatively, the servo force may be measured and the signal directed to a servo system on the control, known as force feedback. Force feedback has been implemented experimentally in some excavators and is useful when excavating mixed material such as large rocks embedded in silt or Research papers haptic technology.
It allows the operator to "feel" and work around unseen obstacles, enabling significant increases in productivity and less risk of damage to the machine.
The first US patent for a tactile telephone was granted to Thomas D. The Interactor vest plugs into the audio output of a stereo, TV, or VCR and the user is provided with controls that allow for adjusting of the intensity of vibration and filtering out of high frequency sounds.
The Interactor Vest is worn over the upper torso and the audio signal is reproduced through a speaker embedded in the vest.
After sellingof its Interactor Vest, Aura began shipping the Interactor Cushion, a device which operates like the Vest but instead of being worn, it's placed against a seat back and the user must lean against it. It would connect to a mobile phone via Bluetooth. Tapping-frequency patterns would identify callers to a mobile and enable the wearer to respond by selected short messages.
It was submitted for a governmental innovation contest and received no award. It was not pursued or published until recovered in It would adapt across all mobile phone and watch brands.
In Apple started to sell a wrist watch which included skin tap sensing of notifications and alerts to mobile phone of the watch wearer. Vibration[ edit ] The majority of electronics offering haptic feedback uses vibrations, and most use a type of eccentric rotating mass ERM actuator, consisting of an unbalanced weight attached to a motor shaft.
As the shaft rotates, the spinning of this irregular mass causes the actuator, and in turn, the attached device, to shake. Some newer devices, such as Apple's MacBooks and iPhones featuring the "Taptic Engine", accomplish their vibrations with a linear resonant actuator LRAwhich moves a mass in a reciprocal manner by means of a magnetic voice coil, similar to how speaker technology translates AC electrical signals into motion of its speaker cone.
LRAs are capable of quicker response times than ERMs, and thus are able to transmit more accurate haptic imagery. Piezoelectric actuators are also employed to produce vibrations, and offer even more precise motion with less noise and in a smaller platform, but require higher voltages than the ERM and LRA implementations, and may be more fragile.
Force feedback[ edit ] Some devices use motors to manipulate the movement of a peripheral held by the user. A common use is in automobile driving video games and simulators, which turn the steering wheel to simulate forces found when cornering a real vehicle. InNovint released the Falconthe first consumer 3D touch device with high resolution three-dimensional force feedback; this allowed the haptic simulation of objects, textures, recoil, momentum, and the physical presence of objects in games.
This type of feedback involves interactions with a system that are in a 3D space around the user. Thus, the user is able to perform actions on a system in the absence of holding a physical input device.

Sri Gurudatta Yadav, Research Scholar, DRKGI, Hyderabad, India. Abstract: Haptic technology, or haptics, is a tactile feedback technology which takes advantage of a user's sense of touch by applying forces, vibrations, and/or motions upon the user.

Based on the same ingredients as mother's love, haptic medicine involves gentle, sometimes playful touch administered by a trusted physician, practitioner or as self-help.
